Thanks for the suggestions everyone. What I know about the height is what the seller told me-84" tall, since the hammer is in transit. Some of the Fairbanks hammers apparently were different heights, depending on the year made, based on the literature I have. I am hoping that there is something like a pulley that can be removed to clear the door.
Making a ramp by the pallet and pulling the hammer off is a great idea. I hope it works, since that would save me on renting something to lift it with. Drilling the floor and pulling from a bar or pipe is also a great idea. The only lift I would need to do then is to lift the hammer up on an elevated base inside the garage, if I decide to elevate it.
A conversation I had today concerning vibration and shock to the floor raised an interesting point. Has anyone ever tried to isolate their hammer on a thick sheet of steel with a number of very stiff springs welded under the plate and perhaps to another bottom plate that rested on the floor, instead of building an isolated concrete foundation? Sort of a spring sandwich between tow heavy plates. Would it lessen the force of the hammer blows too much with the springs compressing any? It seems it would eliminate the need for an isolated foundation.
